One of the reasons Augustine is an interesting character to read is that he represents the interface between church and secularity - in many ways.
He debated whether the church should use state troops to enforce orthodoxy; at first doing so then regretting it. He was the consummate secular politician before conversion. He wrote the great apologetic work 'City of God' which responded to secular fears and accusations against Christianity.
Evangelicalism needs to ponder the complexities of relating to the secular world. The issue is one of those recurring topics that frequently needs re-examination. Bonhoeffer attempted it with his description of the ultimate and penultimate. The ultimate is justification (in the broad sense of standing before the cross and experiencing salvation.) The penultimate is everything that goes before that - human nature (He seems to have coined the term 'mannishness' for this), life experiences, culture, sin and good deeds. He makes the astute point in his Ethics that 'the ultimate is clearly the most important thing, but it does not negate the value of the penultimate.' He makes all kinds of qualifications against potential misunderstandings and builds the case that both those who exalt the penultimate over the ultimate, and those who let the ultimate negate the penultimate, actually do so out of a rebellion against God's power as creator. It is a provocative argument which puts both 'ecological social works idolatry' and 'evangelism only' in the same theological box of sinful rebellion.
Bonhoeffer is one of many theologians who followed in Augustine's footsteps and saw the need to reflect on the relationship between secular and sacred. Others include Luther, Calvin, Thielecke, Aquinas and most recently DA Carson has contributed a stimulating book on the issue.
It occured to me that some stimulus to thinking about the secular/church relationship may be found in recent reporting on the Anglican communions's struggles, and the GAFCON conference. I have noticed an improvement in the level of analysis, even handedness and engagement with issues from secular reporters. In the past I have been very frustrated with Ruth Gledhill's reporting in the Times - she often appeared to misrepresent the conservative viewpoint. However I have been struck that her articles recently make a real effort to understand the conservatives, and she seems to treat them with respect. Similarly, a few nights ago Channel 4 gave Gafcom only about thirty seconds of passing comment - but the BBC gave an in depth summary which even made the point that the issue is the nature of the Gospel. I almost fell off my sofa to hear a newsreader use the word 'Gospel'!
A point in case is this article from the Spectator:
http://www.spectator.co.uk/the-magazine/features/811011/a-very-english-coup-and-the-end-of-our-national-church.thtmlNow of course it is feisty and conservatives are referred to in rather negative terms - that is part of the cut and thrust of comment writing. But I feel the level of analysis and presentation of viewpoints is much more fair than I have in the past been used to.
How can these things be used to aid our ministries while not undermining them? Does the City of God need to ponder again what it means to be 'mingled through time and space with the City of the World'?
